          the duration of the LIBOR Period, such LIBOR Period shall be one
          month.

(b)  The US Agent will promptly notify each US Bank of its receipt of any Notice
     of Borrowing and of the amount of such US Bank's Pro Rata Share of that US
     Loan.

(c)  Each US Bank will make the amount of its Pro Rata Share of each US Loan
     available to the US Agent for the account of the US Borrower at the Agent's
     Payment Office by 11:00 a.m. (San Francisco time) on the Borrowing Date
     requested by the US Borrower in funds immediately available to the US
     Agent. The proceeds of all such Loans will then be made available to the US
     Borrower by the US Agent at such office by crediting the account of the US
     Borrower on the books of BofA with the aggregate of the amounts made
     available to the US Agent by the US Banks and in like funds as received by
     the US Agent.

(d)  After giving effect to any US Loan, unless the US Agent shall otherwise
     consent, there may not be more than six different LIBOR Periods in effect.

2.06 Conversion and Continuation Elections.

(a)  The US Borrower may, upon irrevocable written notice to the US Agent in
     accordance with subsection 2.06(b):

     (i)  elect, as of any Business Day, in the case of Base Rate Loans, or as
          of the last day of the applicable Interest Period, in the case of
          LIBOR Loans, to convert any such US Loans (or any part thereof in an
          amount not less than $1,000,000, or that is in an integral multiple of
          $250,000 in excess thereof) into US Loans of any other Type; or

     (ii) elect, as of the last day of the applicable Interest Period, to
          continue any US Loans having Interest Periods expiring on such day (or
          any part thereof in an amount not less than $1,000,000, or that is in
          an integral multiple of $250,000 in excess thereof);

     provided, that if at any time the aggregate amount of LIBO Rate Loans in
     respect of any US Loan is reduced, by payment, prepayment, or conversion of
     part thereof to be less than $1,000,000, such LIBOR Loans shall
     automatically convert into Base Rate Loans.

(b)  The US Borrower shall deliver a Notice of Conversion/Continuation to be
     received by the US Agent not later than 9:00 a.m. (San Francisco time) at
     least (i) three Business Days in advance of the Conversion/Continuation
     Date, if the US Loans are to be converted into or continued as LIBOR Loans;
     (ii) one Business Day in advance of the Conversion/Continuation Date, if
     the US Loans are to be converted into Base Rate Loans, specifying:

     (A)  the proposed Conversion/Continuation Date;

     (B)  the aggregate amount of US Loans to be converted or continued;

     (C)  the Type of US Loans resulting from the proposed conversion or
          continuation; and

     (D)  the duration of the requested LIBOR Period.

(c)  If upon the expiration of any Interest Period applicable to LIBOR Loans,
     the US Borrower has failed to select timely a new LIBOR Period to be
     applicable to such LIBOR Loans, or if any Default or Event of Default then
     exists, the US Borrower shall be deemed to have elected to convert such
     LIBOR Loans into Base Rate Loans effective as of the expiration date of
     such LIBOR Period.


   34

                                      -28-

(d)  The US Agent will promptly notify each US Bank of its receipt of a Notice
     of Conversion/Continuation, or, if no timely notice is provided by the US
     Borrower, the US Agent will promptly notify each US Bank of the details of
     any automatic conversion. All conversions and continuations shall be made
     ratably according to the respective outstanding principal amounts of the US
     Loans with respect to which the notice was given held by each US Bank.

(e)  Unless the Majority Banks otherwise consent, during the existence of a
     Default or Event of Default, the US Borrower may not elect to have a US
     Loan converted into or continued as an LIBOR Loan.

(f)  After giving effect to any conversion or continuation of US Loans, unless
     the US Agent shall otherwise consent, there may not be more than six
     different Interest Periods in effect.

2.07 Optional Prepayments.

(a)  Subject to Section 4.04, the Company may, at any time or from time to time,
     without penalty, upon not less than one Business Days' irrevocable notice
     to the Canadian Agent, ratably prepay Canadian Loans in whole or in part,
     in minimum amounts of Cdn. $250,000 (or the Equivalent Amount). Such notice
     of prepayment shall specify the date and amount of such prepayment and the
     Type(s) of Loans to be prepaid. The Canadian Agent will promptly notify
     each Canadian Bank of its receipt of any such notice, and of such Bank's
     Pro Rata Share of such prepayment. If such notice is given by the Company,
     the Company shall make such prepayment and the payment amount specified in
     such notice shall be due and payable on the date specified therein,
     together with accrued interest to each such date on the amount prepaid and
     any amounts required pursuant to Section 4.04.

(b)  Subject to Section 4.04, the US Borrower may, at any time or from time to
     time, without penalty, upon not less than one Business Days' irrevocable
     notice to the US Agent, ratably prepay US Loans in whole or in part, in
     minimum amounts of $500,000 or any multiple of $100,000 in excess thereof.
     Such notice of prepayment shall specify the date and amount of such
     prepayment and the Type(s) of Loans to be prepaid. The US Agent will
     promptly notify each US Bank of its receipt of any such notice, and of such
     Bank's Pro Rata Share of such prepayment. If such notice is given by the US
     Borrower, the US Borrower shall make such prepayment and the payment amount
     specified in such notice shall be due and payable on the date specified
     therein, together with accrued interest to each such date on the amount
     prepaid and any amounts required pursuant to Section 4.04.

                                      -29-

2.08 Repayment and Termination Date.

     The Company shall repay to the Canadian Banks the aggregate principal
amount of Canadian Loans outstanding, and the US Borrower shall repay to the US
Banks the aggregate amount of US Loans outstanding, on the day which is the
earlier of (the "Termination Date"):

(a)  the date on which the Commitments terminate in accordance with the
     provisions of this Agreement; and

(b)  the date which is the later of:

     (i)  364 days from the date of this Agreement (the "Initial Term"); and

     (ii) the Extension Date;

     EXCEPT in the case of LIBOR Loans or B/A Equivalent Loans which may be
     outstanding on such date, such date shall be the date which is the later
     of:

     (iii) the Initial Term;

     (iv) the Extension Date; and

     (v)  the date on which the LIBOR Period or Interest Period applicable
          thereto expires (which in no case shall be later than 6 months from
          the end of the Initial Term or from the Extension Date, as
          applicable).

2.09 Extension Date

     "Extension Date" shall mean the date to which the Credit is extended with
the unanimous consent of the Banks, any such extensions to be made only for 364
days at a time. The Company may annually request an extension of the expiry of
the Credit for an additional 364 days period by delivering a request for
extension no later than 90 days prior to the expiry of the Initial Term or any
subsequent extended term. The Canadian Agent shall notify the Company no later
than 30 days following the receipt of a request for extension as to whether or
not the extension has been granted.

                                      -30-

2.10 Interest.

(a)  Each Loan (other than a Letter of Credit) shall bear interest on the
     outstanding principal amount thereof from the applicable Borrowing Date at
     the rate per annum applicable thereto.

(b)  Interest on each Prime Rate Loan, Base Rate Loan, LIBOR Loan and B/A
     Equivalent Loan shall be paid in arrears on each Interest Payment Date.
     Failure to pay interest on the last day of a LIBOR Period shall be subject
     to the provisions of Section 4.04. Interest shall also be paid on the date
     of any prepayment of Loans under Section 2.07 for the portion of the Loans
     so prepaid and upon payment (including prepayment) in full thereof and,
     during the existence of any Event of Default, interest shall be paid on
     demand of the applicable Agent at the request or with the consent of the
     Majority Banks.

(c)  Notwithstanding subsection (a) of this Section, while any Event of Default
     exists or after acceleration, the applicable Borrower shall pay interest
     (after as well as before entry of judgment thereon to the extent permitted
     by law) on the principal amount of all outstanding Obligations, at a rate
     per annum which is determined by adding 3% per annum to the interest rate
     then in effect for such Loans; provided, however, that, on and after the
     expiration of any Interest Period applicable to any LIBOR Loan or B/A
     Equivalent Loan outstanding on the date of occurrence of such Event of
     Default or acceleration, the principal amount of such Loan shall, during
     the continuation of such Event of Default or after acceleration, bear
     interest at a rate per annum equal to the Base Rate plus 3% and the
     Applicable Margin in the case of LIBOR Loans and Prime Rate plus 3% and the
     Applicable Margin in the case of B/A Equivalent Loans.

(d)  Anything herein to the contrary notwithstanding, the obligations of each
     Borrower to any Bank hereunder shall be subject to the limitation that
     payments of interest shall not be required for any period for which
     interest is computed hereunder, to the extent (but only to the extent) that
     contracting for or receiving such payment by such Bank would be contrary to
     the provisions of any law applicable to such Bank limiting the highest rate
     of interest that may be lawfully contracted for, charged or received by
     such Bank, and in such event the applicable Borrower shall pay such Bank
     interest at the highest rate permitted by applicable law.


   37

                                      -31-

2.11 Fees.

(a)  Arrangement, Agency Fees. The Borrowers shall pay such fees, which shall
     include arrangement and agency fees, to the Agents and/or the Banks as
     required by separate letter agreements ("Fee Letters").

(b)  Commitment Fees. The Company shall pay to the Canadian Agent and the US
     Borrower shall pay to the US Agent for the account of each applicable Bank
     a commitment fee of 0.375% per annum of the daily unused portion of such
     Bank's Commitment (determined as an average), computed on a quarterly basis
     in arrears on the last Business Day of each calendar quarter based upon the
     daily utilization for that quarter as calculated by the Agents. Such
     commitment fee shall accrue from the Closing Date to the Termination Date
     and shall be due and payable quarterly in arrears on the last Business Day
     of each calendar quarter commencing on first calendar quarter following the
     Closing Date through the Termination Date, with the final payment to be
     made on the Termination Date; provided that, in connection with any
     reduction or termination of Commitments under Section 2.07, the accrued
     commitment fee calculated for the period ending on such date shall also be
     paid on the date of such reduction or termination, with the following
     quarterly payment being calculated on the basis of the period from such
     reduction or termination date to such quarterly payment date. The
     commitment fees provided in this subsection shall accrue at all times after
     the above-mentioned commencement date, including at any time during which
     one or more conditions in Article V are not met.

2.12 Computation of Fees and Interest.

(a)  All computations of interest for Prime Rate Loans and B/A Equivalent Loans
     shall be made on the basis of a year of 365 or 366 days, as the case may
     be, and actual days elapsed. All other computations of fees and interest
     shall be made on the basis of a 360-day year and actual days elapsed (which
     results in more interest being paid than if computed on the basis of a 365
     day year). Interest and fees shall accrue during each period during which
     interest or such fees are computed from the first day thereof to the last
     day thereof.

(b)  Each determination of an interest rate by an Agent shall be conclusive and
     binding on the Borrowers and the Banks in the absence of manifest error.
     The Agent will, at the request of a Borrower or any Bank, deliver to such
     Borrower or the Bank, as the case may be, a statement showing the
     quotations used by such Agent in determining any interest rate and the
     resulting interest rate.

(c)  Each rate of interest which is calculated with reference to a period (the
     "deemed interest period") that is less than the actual number of days in
     the calendar year of calculation is, for the purposes of the Interest Act
     (Canada), equivalent to a rate based on a calendar year


   38

                                      -32-

     calculated by multiplying such rate of interest by the actual number of
     days in the calendar year of calculation and dividing by the number of days
     in the deemed interest period.

2.13 Payments by a Borrower

(a)  All payments to be made by a Borrower shall be made without set off,
     recoupment or counterclaim. Except as otherwise expressly provided herein,
     all payments by the Company shall be made to the Canadian Agent and all
     payments by the US Borrower shall be made to the US Agent for the account
     of the applicable Banks at the applicable Agent's Payment Office, and shall
     be made in dollars or Cdn. Dollars, as applicable, and in immediately
     available funds, no later than 12:00 noon Toronto time on the date
     specified herein for payments to the Canadian Agent, and no later than
     11:00 a.m. San Francisco time for payments to the US Agent. The applicable
     Agent will promptly distribute to each applicable Bank its Pro Rata Share
     (or other applicable share as expressly provided herein) of such payment in
     like funds as received. Any payment received by the applicable Agent later
     than the times specified above shall be deemed to have been received on the
     following Business Day and any applicable interest or fee shall continue to
     accrue.

(b)  Subject to the provisions set forth in the definition of "Interest Period"
     herein, whenever any payment is due on a day other than a Business Day,
     such payment shall be made on the following Business Day, and such
     extension of time shall in such case be included in the computation of
     interest or fees, as the case may be.

(c)  Unless an Agent receives notice from the applicable Borrower prior to the
     date on which any payment is due to the Banks that the applicable Borrower
     will not make such payment in full as and when required, the Agent may
     assume that the applicable Borrower has made such payment in full to the
     Agent on such date in immediately available funds and the Agent may (but
     shall not be so required), in reliance upon such assumption, distribute to
     each Bank on such due date an amount equal to the amount then due such
     Bank. If and to the extent the applicable Borrower has not made such
     payment in full to the Agent, each Bank shall repay to the Agent on demand
     such amount distributed to such Bank, together with interest thereon at the
     Federal Funds Rate for each day from the date such amount is distributed to
     such Bank until the date repaid.

2.14 Payments by the Banks to the Agents.

(a)  Unless the applicable Agent receives notice from a Bank on or prior to the
     Closing Date or, with respect to any Borrowing after the Closing Date, at
     least one Business Day prior to the date of such Borrowing, that such Bank
     will not make available as and when required hereunder to the applicable
     Agent for the account of the applicable Borrower the amount of that Bank's
     Pro Rata Share of the Borrowing, such Agent may assume that each Bank has
     made such amount available to the applicable Agent in immediately available


   39

                                      -33-

     funds on the Borrowing Date and such Agent may (but shall not be so
     required), in reliance upon such assumption, make available to the
     applicable Borrower on such date a corresponding amount. If and to the
     extent any Bank shall not have made its full amount available to the
     applicable Agent in immediately available funds and the applicable Agent in
     such circumstances has made available to the applicable Borrower such
     amount, that Bank shall on the Business Day following such Borrowing Date
     make such amount available to such Agent, together with interest at the
     Federal Funds Rate for each day during such period. A notice of the
     applicable Agent submitted to any Bank with respect to amounts owing under
     this subsection shall be conclusive, absent manifest error. If such amount
     is so made by the Agent, such payment to the applicable Agent shall
     constitute such Bank's Loan on the date of Borrowing for all purposes of
     this Agreement. If such amount is not made available to the applicable
     Agent on the Business Day following the Borrowing Date, the applicable
     Agent will notify the applicable Borrower of such failure to fund and, upon
     demand by the Agent, the applicable Borrower shall pay such amount to the
     applicable Agent for the Agent's account, together with interest thereon
     for each day elapsed since the date of such Borrowing, at a rate per annum
     equal to the interest rate applicable at the time to the Loans comprising
     such Borrowing.

(b)  The failure of any Bank to make any Loan on any Borrowing Date shall not
     relieve any other Bank of any obligation hereunder to make a Loan on such
     Borrowing Date, but no Bank shall be responsible for the failure of any
     other Bank to make the Loan to be made by such other Bank on any Borrowing
     Date.

2.15 Sharing of Payments, Etc. If, other than as expressly provided elsewhere
herein, any Bank shall obtain on account of the Loans made by it any payment
(whether voluntary, involuntary, through the exercise of any right of set off,
or otherwise) in excess of its Pro Rata Share (or other share contemplated
hereunder), such Bank shall immediately (a) notify the applicable Agent of such
fact, and (b) purchase from the other Canadian Banks, in the case of Canadian
Loans and US Banks, in the case of US Loans, such participations in the Loans
made by them as shall be necessary to cause such purchasing Bank to share the
excess payment pro rata with each of them; provided, however, that if all or any
portion of such excess payment is thereafter recovered from the purchasing Bank,
such purchase shall to that extent be rescinded and each other Bank shall repay
to the purchasing Bank the purchase price paid therefor, together with an amount
equal to such paying Bank's Pro Rata Share (according to the proportion of (i)
the amount of such paying Bank's required repayment to (ii) the total amount so
recovered from the purchasing Bank) of any interest or other amount paid or
payable by the purchasing Bank in respect of the total amount so recovered. Each
Borrower agrees that any Bank so purchasing a participation from another Bank
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set off, but subject to Section 11.10) with respect to
such participation as fully as if such Bank were the direct creditor of the
Borrower in the amount of such participation. The applicable Agent will keep
records (which shall be conclusive and binding in the absence of manifest error)


   40

                                      -34-

of participations purchased under this Section and will in each case notify the
Banks following any such purchases or repayments.

2.16 Security and Guarantee.

(a)  All obligations of each Borrower and the Guarantors under this Agreement
     and all other Loan Documents shall be secured in accordance with the
     Collateral Documents.

(b)  All obligations of each Borrower under this Agreement, and all other Loan
     Documents shall be unconditionally guaranteed by each Guarantor pursuant to
     the Guarantees.

2.17 Allocation of Total Commitment.

(a)  The Borrowers shall be entitled from time to time prior to the Termination
     Date to allocate such portions of the Total Commitment as it determines as
     between the Total Canadian Commitment and Total US Commitment by delivering
     a request hereunder (the "Reallocation Request") substantially in the form
     of Exhibit E to each of the Agents provided that:

     (i)  the Reallocation Request shall be given at least three Business Days
          prior to it becoming effective;

     (ii) at the time the Reallocation Request becomes effective, no Default or
          Event of Default has occurred and is continuing;

    (iii) after giving effect to the Reallocation Request, the aggregate of the
          Total Canadian Commitment and the Total US Commitment does not exceed
          the then current Total Commitment;

     (iv) if any such Reallocation Request would result in the Equivalent Amount
          in Canadian Dollars of the Canadian Loan or the US Loan, as
          applicable, then outstanding to the Company or the US Borrower, as
          applicable, exceeding the Total Canadian Commitment or the Total US
          Commitment, then, concurrently with any such Reallocation Request
          becoming effective, the Company shall ensure that all payments
          necessary are made by it or the US Borrower, as applicable and
          including, without limitation, any costs payable pursuant to Section
          4.04, so that the Equivalent Amount in Canadian dollars of the
          Canadian Loan and the US Loan after giving effect to any such
          Reallocation Request do not exceed the Total Canadian Commitment and
          the Total US Commitment, respectively;

     (v)  a Reallocation Request shall not be given more than four (4) times in
          any calendar year; and


   41

                                      -35-

     (vi) a Reallocation Request shall be for a minimum amount of $1,000,000 or
          any multiples of $1,000,000 in excess thereof.

(b)  The Canadian Agent shall notify the Canadian Banks and the US Agent shall
     notify the US Banks of the receipt of a Reallocation Request and the
     resulting Pro Rata Shares.

2.18 Swing Line Facility.

(a)  Upon the satisfaction of the conditions precedent set forth in Article V
     and after execution and delivery by the US Borrower of the Swing Line
     Lender's usual and customary account operating documentation, as
     applicable, from and including the date of this Agreement and prior to the
     Termination Date, the Swing Line Lender agrees, on the terms and conditions
     set forth in this Agreement, to make Swing loans to the US Borrower from
     time to time on any Business Day, in an amount not to exceed $1 million
     (such facility the "Swing Line Facility" and Loans thereunder "Swing Line
     Loans"); provided, however, at no time shall the aggregate of the principal
     amount of the Swing Line Loans and the Equivalent Amount of all other Loans
     exceed the Total Commitment; and provided, further, that at no time shall
     the sum of (i) the outstanding amount of the Swing Line Loans, plus (ii)
     the outstanding amount of Loans made by the US Banks, pursuant to Section
     2.05 (after giving effect to any concurrent payment of Loans), exceed the
     Total US Commitment at such time. Subject to the terms of this Agreement,
     the US Borrower may borrow, repay and re-borrow Swing Line Loans at any
     time prior to the Termination Date.

(b)  The proceeds from any and all Swing Line Loans shall only be used to repay
     the US Borrower's master concentration account maintained at a NationsBank,
     N.A. branch in Nashville, Tennessee.

(c)  NationsBank, N.A. as attorney for the US Borrower shall deliver to the US
     Agent a Notice of Borrowing not later than 10:00 a.m. (San Francisco time)
     on the Borrowing Date of each Swing Line Loan, specifying (i) the
     applicable Borrowing Date (which date shall be a Business Day and may be
     the same date as the Notice of Borrowing is given); (ii) the aggregate
     amount of the requested Swing Line Loans; and (iii) instructions for the
     disbursement of the proceeds of such Swing Line Loan to the US Borrower's
     master concentration account at NationsBank, N.A. The Swing Line Loans
     shall at all times be US Base Rate Loans but shall not be subject to the
     minimum borrowing amounts specified in Section 2.05(a)(A).

(d)  Each Swing Line Loan shall be paid in full by the US Borrower on or before
     the earlier of (the "Swing Line Repayment Date"): (i) the fifth Business
     Day after the Borrowing Date for such Swing Line Loan (subject to the
     minimum borrowing amounts specified in Section 2.05(a)(A)); or (ii) the
     outstanding balance of the Swing Line Loans reaching $500,000 or more; or
     (iii) the Termination Date. The US Borrower may at any time,


   42

                                      -36-

     without penalty or premium, repay all outstanding Swing Line Loans upon
     notice to the US Agent. In addition, the US Agent shall on the Swing Line
     Repayment Date, notify each US Bank (with a copy to the US Borrower) and
     advise it to make a Base Rate Loan in the amount of such US Bank's Pro Rata
     Share of such Swing Line Loan, for the purpose of repaying such Swing Line
     Loan. Not later than 11:00 a.m. (San Francisco time) on the day following
     the date of any notice from the US Agent to the US Banks received pursuant
     to this Section 2.18(d), each US Bank shall make available its required
     loan or loans, in funds immediately available to the US Agent at the US
     Agent's Designated Account. Loans made by the US Banks in repayment of a
     Swing Line Loan pursuant to this Section 2.18(d) shall be US Base Rate
     Loans and subject to the minimum borrowing amount specified in Section
     2.05(a)(A). Unless a US Bank shall have notified the US Agent, prior to its
     making any Swing Line Loan, that any applicable condition precedent set
     forth in Article V had not been satisfied, such US Bank's obligation to
     make Loans pursuant to this Section 2.18(d) to repay Swing Line Loans shall
     be unconditional, continuing, irrevocable and absolute and shall not be
     affected by any circumstances, including, without limitation, (i) any
     set-off, counterclaim, defence or other claim which the US Bank may have
     against the US Agent or any other Person; (ii) the occurrence and
     continuance of an Event of Default; (iii) any Material Adverse Change; or
     (iv) any other circumstance, happening or event whatsoever. In the event
     that any US Bank fails to make payment to the US Agent of any amount due
     under this Section 2.18(d), the US Agent shall be entitled to receive,
     retain and apply against such obligation owing to the Swing Line Lender the
     principal and interest otherwise payable to the US Bank hereunder until the
     Swing Line Lender receives such payment from the US Bank or such obligation
     is otherwise fully satisfied. In addition to the foregoing, if, for any
     reason any US Bank fails to make payment to the US Agent of any amount due
     under this Section 2.18(d), such US Bank shall be deemed to have
     unconditionally and irrevocably purchased from the Swing Line Lender,
     without recourse or warranty, an undivided interest and participation in
     the applicable Swing Line Loan in the amount of such Loan, and such
     interest and participation may be recovered from such US Bank together with
     interest thereon at the Federal Funds Rate for each day during the period
     commencing on the date of demand and ending on the date such amount is
     received. On the Termination Date, the US Borrower shall repay in full the
     outstanding principal balance of the Swing Line Loans and all interest
     accrued thereon.

                              THE LETTERS OF CREDIT

3.01 Letters of Credit. On the terms and conditions set forth herein (i) the
Issuing Banks agree, (A) from time to time on any Business Day during the period
from the Closing Date to the day which is five days prior to the Termination
Date to issue Letters of Credit for the account of the Company in the case of
Cdn.$ L/Cs and to the US Borrower in the case of US$ L/Cs, and to amend or renew
Letters of Credit previously issued by it, in accordance with Sections 3.02(b)
and (c), and (B) to honour drafts under the Letters of Credit; and (ii) the
Canadian Banks severally agree to participate in Letters of Credit issued for
the account of the Company and the US Banks severally agree to participate in
Letters of Credit issued for the amount of the US Borrower, as applicable;
provided, that the Issuing Bank shall not be obligated to Issue, and no Bank
shall be obligated to participate in, any Letter of Credit if as of the date of
Issuance of such Letter of Credit (the "Issuance Date") (1) the Equivalent
Amount of all L/C Obligations plus the Equivalent Amount of all Loans (excluding
the issuance of such L/Cs) exceeds the combined Commitments, or, (2) the
participation of any Bank in the Equivalent Amount of all L/C Obligations plus
the Equivalent Amount of all outstanding Loans exceeds such Bank's Commitment.
Within the foregoing limits, and subject to the other terms and conditions
hereof, the applicable Borrower's ability to obtain Letters of Credit shall be
fully revolving, and, accordingly, the applicable Borrower may, during the
foregoing period, obtain Letters of Credit to replace Letters of Credit which
have expired or which have been drawn upon and reimbursed. Upon issuance or
renewal by the Issuing Bank of an L/C, the Borrower for whose benefit or at
whose request such L/C was issued or renewed shall pay to the Issuing Bank (or
to the applicable Agent on behalf of the Issuing Bank) the L/C Issuance Fee and
L/C Fee. The L/C Issuance Fee and the L/C Fee shall apply to each Letter of
Credit issued, including all renewals or amendments pursuant to Sections 3.02.

3.02 Issuance, Amendment and Renewal of Letters of Credit

(a)  Each Letter of Credit shall be issued upon the irrevocable written request
     of the applicable Borrower received by the Issuing Bank at least three days
     (or such shorter time as the Issuing Bank may agree in a particular
     instance in its sole discretion) prior to the proposed Issuance Date, with
     a copy of such written request delivered to the Applicable Agent. The
     issuance of a Letter of Credit shall be made no later than noon (Toronto
     time) on the Issuance Date. Each such request for issuance of a Letter of
     Credit shall be by facsimile, confirmed immediately in an original writing,
     in the form of an L/C Application, and shall specify in form and detail
     satisfactory to the Issuing Bank (i) the proposed date of issuance of the
     Letter of Credit (which shall be a Business Day); (ii) the face amount of
     the Letter of Credit; (iii) the expiry date of the Letter of Credit; (iv)
     the name and address of the beneficiary thereof; (v) the documents to be
     presented by the beneficiary of the Letter of Credit in case of any drawing
     thereunder; (vi) the full text of any certificate to be


   44

                                      -38-

     presented by the beneficiary in case of any drawing thereunder; and (vii)
     such other matters as the Issuing Bank may require.

(b)  From time to time while a Letter of Credit is outstanding and prior to the
     Termination Date, the Issuing Bank will, upon the written request of the
     applicable Borrower received by the Issuing Bank at least three days (or
     such shorter time as the Issuing Bank may agree in a particular instance in
     its sole discretion) prior to the proposed date of amendment, amend any
     Letter of Credit issued by it. Each such request for amendment of a Letter
     of Credit shall be made by facsimile, confirmed immediately in an original
     writing, made in the form of an L/C Amendment Application and shall specify
     in form and detail satisfactory to the Issuing Bank: (i) the Letter of
     Credit to be amended; (ii) the proposed date of amendment of the Letter of
     Credit (which shall be a Business Day); (iii) the nature of the proposed
     amendment; and (iv) such other matters as the Issuing Bank may require. The
     Issuing Bank shall be under no obligation to amend any Letter of Credit if:
     (A) the Issuing Bank would have no obligation at such time to issue such
     Letter of Credit in its amended form under the terms of this Agreement; or
     (B) the beneficiary of any such Letter of Credit does not accept the
     proposed amendment to the Letter of Credit. The Agent will promptly notify
     the Lenders of the receipt by it of any L/C Application, L/C Amendment
     Application or notice of renewal.

(c)  The Issuing Bank and the Banks agree that, while a Letter of Credit is
     outstanding and prior to the Termination Date, at the option of the
     applicable Borrower at least five days (or such shorter time as the Issuing
     Bank may agree in a particular instance in its sole discretion) prior to
     the proposed date of notification of renewal, the Issuing Bank shall be
     entitled to authorize the renewal of any Letter of Credit issued by it.
     Each such request for renewal of a Letter of Credit shall be made by
     facsimile, confirmed immediately in an original writing, in the form of an
     L/C Amendment Application, and shall specify in form and detail
     satisfactory to the Issuing Bank: (i) the Letter of Credit to be renewed;
     (ii) the proposed date of notification of renewal of the Letter of Credit
     (which shall be a Business Day); (iii) the revised expiry date of the
     Letter of Credit; and (iv) such other matters as the Issuing Bank may
     require.

3.03 Payments, Risk Participations, Drawings and Reimbursements

(a)  The applicable Borrower shall provide for the payment to the Canadian Agent
     in the case of Cdn.$ L/Cs, and to the US Agent, in the case of US$ L/Cs, of
     the full face amount of each Letter of Credit on the earlier of (i) the
     Honour Date (as defined in Section 3.03(c) below), and (ii) demand for
     payment in accordance with 9.02.

(b)  Immediately upon the Issuance of each Letter of Credit, each Canadian Bank
     in the case of Cdn.$ L/Cs and each US Bank in the case of US$ L/Cs shall be
     deemed to, and hereby irrevocably and unconditionally agrees to, purchase
     from the Issuing Bank a participation


   45

                                      -39-

     in such Letter of Credit and each drawing thereunder in an amount equal to
     the product of (i) the Pro Rata Share of such Bank, times (ii) the maximum
     amount available to be drawn under such Letter of Credit and the amount of
     such drawing, respectively. For purposes of Section 2.01, each Issuance of
     a Letter of Credit shall be deemed to utilize the Commitment of each
     applicable Bank by an amount equal to the amount of such participation.
     Upon the Issuance of each Letter of Credit, the applicable Agent, on behalf
     of the Issuing Bank, shall notify each applicable Bank of the amount of
     such Bank's participation and the proportionate share of the L/C Fee.

(c)  In the event of any request for a drawing under a Letter of Credit by the
     beneficiary or transferee thereof, the Issuing Bank will promptly notify
     the applicable Borrower. The applicable Borrower shall reimburse the
     Issuing Bank (by an L/C Loan or otherwise) prior to 12:00 Noon (Toronto
     time) on each date that any amount is paid by the Issuing Bank under any
     such Borrower's Letter of Credit (each such date, an "Honour Date"), in an
     amount equal to the amount so paid by the Issuing Bank. In the event that
     the applicable Borrower fails to reimburse the Issuing Bank for the full
     amount of any drawing under any such Borrower's Letter of Credit by 12:00
     Noon (Toronto time) on the Honour Date, the Issuing Bank will promptly
     notify the applicable Agent thereof, and the applicable Borrower shall be
     deemed to have requested that Base Rate or Prime Rate Loans, as the case
     may be, in an aggregate amount equal to the unreimbursed drawing made by
     the Banks to be disbursed on the Honour Date under such Letter of Credit,
     subject to the amount of the unutilized portion of the Bank's Commitment.
     Any notice given by the Issuing Bank pursuant to this clause may be oral if
     immediately confirmed in writing (including by facsimile); provided, that
     the lack of such an immediate confirmation shall not affect the
     conclusiveness or binding effect of such notice.

(d)  Each Bank shall upon any notice pursuant to Section 3.03(c) make available
     to the relevant Issuing Bank an amount in immediately available funds equal
     to its Pro Rata Share of the amount of the unreimbursed drawing, whereupon
     the applicable Banks shall each be deemed to have made a Prime Rate Loan or
     Base Rate Loan, or the case may be, to the applicable Borrower. If any Bank
     so notified fails to make available to the applicable Issuing Bank the
     amount of such Lender's Pro Rata Share of the amount of the unreimbursed
     drawing by no later than 2:00 p.m. (Toronto time) on the Honour Date, then
     interest shall accrue on such Bank's obligation to make such payment, from
     the Honour Date to the date such Bank makes such payment, at a rate per
     annum equal to the Federal Funds Rate in effect from time to time during
     such period.

(e)  Each Bank's obligation in accordance with this Agreement to make the Loans
     or L/C Advances, as contemplated by this Section 3.03, as a result of a
     drawing under a Letter of Credit, shall be absolute and unconditional and
     without recourse to the applicable Issuing Bank and shall not be affected
     by any circumstance, including (i) any set-off, counterclaim, recoupment,
     defence or other right which such Bank may have against the


   46

                                      -40-

     Issuing Bank, the Borrower or any other Person for any reason whatsoever;
     (ii) the occurrence or continuance of a Default, an Event of Default or a
     Material Adverse Effect; or (iii) any other circumstance, happening or
     event whatsoever, whether or not similar to any of the foregoing.

3.04 Repayment of Participations

(a)  Upon (and only upon) receipt by the Issuing Bank of immediately available
     funds from the applicable Borrower (i) in reimbursement of any payment made
     by the Issuing Bank under the Letter of Credit with respect to which any
     Bank has paid to the Issuing Bank for such participation in the Letter of
     Credit pursuant to Section 3.03 or (ii) in payment of interest thereon, the
     Issuing Bank will pay to each Bank in the same funds as those received by
     the Issuing Bank, the amount of such Bank's Pro Rata Share of such funds,
     and the Issuing Bank shall receive the amount of the Pro Rata Share of such
     funds of any Bank that did not so pay.

(b)  If the Issuing Bank is required at any time to return to the Company or the
     US Borrower, or to a trustee, receiver, liquidator, custodian, or any
     official in any Insolvency Proceeding, any portion of the payments made by
     the Company or US Borrower to the Issuing Bank pursuant to Section 3.04(a)
     in reimbursement of a payment made under a Letter of Credit or interest or
     fee thereon, each Bank shall, on demand of the Agent, forthwith return to
     the Agent or the Issuing Bank the amount of its Pro Rata Share of any
     amounts so returned by the Issuing Bank plus interest thereon from the date
     such demand is made to the date such amounts are returned by such Bank to
     the Agent or the Issuing Bank, at a rate per annum equal to the Federal
     Funds Rate in effect from time to time.

3.05 Obligations Absolute The obligations of the applicable Borrower under this
Agreement and any L/C-related document to reimburse the Issuing Bank for a
drawing under a Letter of Credit, and to repay any L/C Loan and any drawing
under a Letter of Credit converted into Base Rate Loans, shall be unconditional
and irrevocable, and shall be paid strictly in accordance with the terms of this
Agreement and each such other L/C-related document under all circumstances. The
obligations of a Borrower to reimburse the Issuing Bank (or the applicable Agent
on behalf of the Issuing Bank) for payment to a beneficiary of an L/C shall
survive termination of this Agreement and shall, except for matters arising from
the Issuing Bank's wilful misconduct or negligence (which shall include
instances where the fraud by a beneficiary has been established to the knowledge
of the Issuing Bank so as to make the fraud clear or obvious to the Issuing
Bank), be absolute and unconditional and shall not be reduced by a demand or
other request for payment of the L/C (a "Demand") paid or acted upon being
invalid, insufficient, fraudulent or forged, or be subject to any defence or be
affected by any right of set-off, counterclaim or recoupment which such Borrower
may now or hereafter have against the beneficiary, the Issuing Bank or any other
Person for any reason whatsoever, including the fact that the Issuing Bank or
its correspondents paid a Demand or Demands (if applicable) aggregating up to
the amount of the


   47

                                      -41-

L/C notwithstanding any contrary instructions from a Borrower to the Issuing
Bank or applicable Agent. Any action, inaction or omission taken or suffered by
the Issuing Bank or by the Issuing Bank's correspondent under or in connection
with an L/C or any Demand, if in good faith and in conformity with foreign, US
or Canadian laws, regulations or customs applicable thereto shall be binding on
each Borrower and their respective subsidiaries and shall not place either Agent
or the Issuing Bank or any of its correspondents under any resulting liability
to the Borrowers, their subsidiaries or any of them. Without limiting the
generality of the foregoing, the Issuing Bank and its correspondents may
receive, accept or pay as complying with the terms of the L/C, any Demand
otherwise in order which may be signed by, or issued to, any administrator,
executor, trustee in bankruptcy, receiver or other Person acting as a
representative of, or in place of, the beneficiary. Each of the Borrowers
covenants that, in the absence of fraud on the part of the beneficiary of an
L/C, it will not take steps, issue any instructions to the Issuing Bank or any
correspondence or institute any proceedings intended to derogate from the right
or ability of the Issuing Bank or its correspondents to honour or pay any
Demand.

3.06 Cash Collateral Pledge. Upon (a) the request of the applicable Agent or the
Majority Lenders, if the Issuing Bank has honoured any full or partial drawing
request on any Letter of Credit and such drawing has resulted in an L/C Loan
hereunder at a time when any Event of Default has occurred and is continuing, or
(b) if, as of the Termination Date, any Letters of Credit may for any reason
remain outstanding and partially or wholly undrawn, then, the applicable
Borrower shall immediately Cash Collateralize the L/C Obligations in an amount
equal to such L/C Obligations.

                                   ARTICLE IV
                     TAXES, YIELD PROTECTION AND ILLEGALITY

4.01 Taxes.

(a)  Subject to Section 4.01(b), any and all payments by the Company or the US
     Borrower to each Bank or the Agents under this Agreement and any other Loan
     Document shall be made free and clear of, and without deduction or
     withholding for, any Taxes. In addition, the Company or the US Borrower, as
     the case may be, shall pay all Other Taxes.

(b)  If the Company or the US Borrower shall be required by law to deduct or
     withhold any Taxes, Other Taxes or Further Taxes from or in respect of any
     sum payable hereunder to any Bank or the Agents, then:

     (i)  the sum payable shall be increased as necessary so that, after making
          all required deductions and withholdings (including deductions and
          withholdings applicable to additional sums payable under this
          Section), such Bank or the Agents, as the case may be, receives and
          retains an amount equal to the sum it would have received and retained
          had no such deductions or withholdings been made;


   48

                                      -42-

     (ii) the Company or the US Borrower, as the case may be, shall make such
          deductions and withholdings;

    (iii) the Company or the US Borrower, as the case may be, shall pay the
          full amount deducted or withheld to the relevant taxing authority or
          other authority in accordance with applicable law; and

     (iv) the Company or the US Borrower, as the case may be, shall also pay to
          each Bank or the Agents for the account of such Bank, at the time
          interest is paid, Further Taxes in the amount that the respective Bank
          specifies as necessary to preserve the after-tax yield the Bank would
          have received if such Taxes, Other Taxes or Further Taxes had not been
          imposed.

(c)  The Company agrees to indemnify and hold harmless each Bank and the Agents
     for the full amount of i) Taxes, ii) Other Taxes, and iii) Further Taxes
     paid by Banks in the amount that the respective Bank specifies as necessary
     to preserve the after-tax yield the Bank would have received if such Taxes,
     Other Taxes or Further Taxes had not been imposed, and any liability
     (including penalties, interest, additions to tax and expenses) arising
     therefrom or with respect thereto, whether or not such Taxes, Other Taxes
     or Further Taxes were correctly or legally asserted. Payment under this
     indemnification shall be made within 30 days after the date the Bank or the
     Agents make written demand therefor.

(d)  Under this Section within 30 days after the date of any payment by the
     Company of Taxes, Other Taxes or Further Taxes, under Section 4.01(b) the
     Company or the US Borrower, as the case may be, shall furnish to each Bank
     or the Agents the original or a certified copy of a receipt evidencing
     payment thereof, or other evidence of payment satisfactory to such Bank or
     the Agents.

(e)  If the Company or the US Borrower, as the case may be, is required to pay
     any amount to any Bank or the Agents pursuant to subsection (b) or (c) of
     this Section, then such Bank shall use reasonable efforts (consistent with
     legal and regulatory restrictions) to change the jurisdiction of its
     Lending Office so as to eliminate any such additional payment by the
     Company or the US Borrower which may thereafter accrue, if such change in
     the sole judgment of such Bank is not otherwise disadvantageous to such
     Bank.

4.02 Illegality.

(a)  If any Bank determines that the introduction of any Requirement of Law, or
     any change in any Requirement of Law, or in the interpretation or
     administration of any Requirement of Law, has made it unlawful, or that any
     central bank or other Governmental Authority has asserted that it is
     unlawful, for any Bank or its applicable Lending Office to make LIBOR
     Loans, then, on notice thereof by the Bank to the Company through the
     applicable


   49

                                      -43-

     Agent, any obligation of that Bank to make LIBOR Loans shall be suspended
     until the Bank notifies the applicable Agent and the Company that the
     circumstances giving rise to such determination no longer exist.

(b)  If a Bank determines that it is unlawful to maintain any LIBOR Loan, each
     Borrower shall, upon its receipt of notice of such fact and demand from
     such Bank (with a copy to the applicable Agent), prepay in full such LIBOR
     Loans of that Bank then outstanding, together with interest accrued thereon
     and amounts required under Section 4.04, either on the last day of the
     Interest Period thereof, if the Bank may lawfully continue to maintain such
     LIBOR Loans to such day, or immediately, if the Bank may not lawfully
     continue to maintain such LIBOR Loan. If any Borrower is required to so
     prepay any LIBOR then concurrently with such prepayment, the Borrower shall
     borrow from the affected Bank, in the amount of such repayment, a Base Rate
     Loan.

(c)  If the obligation of any Bank to make or maintain LIBOR Loans has been so
     terminated or suspended, the Borrower may elect, by giving notice to the
     Bank through the applicable Agent that all Loans which would otherwise be
     made by the Bank as LIBOR Loans shall be instead a Base Rate Loan.

(d)  Before giving any notice to an Agent under this Section, the affected Bank
     shall designate a different Lending Office with respect to its LIBOR Loans
     if such designation will avoid the need for giving such notice or making
     such demand and will not, in the judgment of the Bank, be illegal or
     otherwise disadvantageous to the Bank.

4.03 Increased Costs and Reduction of Return.

(a)  If any Bank determines that, due to either (i) the introduction of or any
     change in or in the interpretation of any law or regulation or (ii) the
     compliance by that Bank with any guideline or request from any central bank
     or other Governmental Authority (whether or not having the force of law),
     there shall be any increase in the cost to such Bank of agreeing to make or
     making, funding or maintaining any LIBOR Loans, B/A Equivalent Loans or
     participating in L/Cs, then the Company or the US Borrower shall be liable
     for, and shall from time to time, upon demand (with a copy of such demand
     to be sent to the Agent), pay to the applicable Agent for the account of
     such Bank, additional amounts as are sufficient to compensate such Bank for
     such increased costs.

(b)  If any Bank shall have determined that (i) the introduction of any Capital
     Adequacy Regulation, (ii) any change in any Capital Adequacy Regulation,
     (iii) any change in the interpretation or administration of any Capital
     Adequacy Regulation by any central bank or other Governmental Authority
     charged with the interpretation or administration thereof, or (iv)
     compliance by the Bank (or its Lending Office) or any corporation
     controlling the Bank with any Capital Adequacy Regulation, affects or would
     affect the amount of capital


   50

                                      -44-

     required or expected to be maintained by the Bank or any corporation
     controlling the Bank and (taking into consideration such Bank's or such
     corporation's policies with respect to capital adequacy and such Bank's
     desired return on capital) determines that the amount of such capital is
     increased as a consequence of its Commitments, loans, credits or
     obligations under this Agreement, then, upon demand of such Bank to any
     Borrower through the applicable Agent, such Borrower shall pay to the Bank,
     from time to time as specified by the Bank, additional amounts sufficient
     to compensate the Bank for such increase.

4.04 Funding Losses. Each Borrower shall reimburse each Bank and hold each Bank
harmless from any loss or expense which the Bank may sustain or incur as a
consequence of:

(a)  the failure of such Borrower to make on a timely basis any payment of
     principal or interest of any LIBOR Loan or B/A Equivalent Loan;

(b)  the failure of such Borrower to borrow, continue or convert a Loan after
     the Borrower has given (or is deemed to have given) a Notice of Borrowing
     or Notice of Conversion/Continuation;

(c)  the failure of such Borrower to make any prepayment in accordance with any
     notice delivered under Section 2.07;

(d)  the prepayment (including pursuant to Section 2.07) or other payment
     (including after acceleration thereof) of a LIBOR Loan or B/A Equivalent
     Loan on a day that is not the last day of the relevant Interest Period; or

(e)  the automatic conversion of a LIBOR Loan or a B/A Equivalent Loan under
     Section 2.04 or 2.06, as the case may be on a day that is not the last day
     of a relevant Interest Period,

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its LIBOR Loans or B/A Equivalent Loans or
from fees payable to terminate the deposits from which such funds were obtained.

4.05 Inability to Determine Rates. If an Agent determines that for any reason
adequate and reasonable means do not exist for determining the LIBO Rate for any
requested LIBOR Period with respect to a proposed LIBOR Loan, or that the LIBO
Rate applicable does not adequately and fairly reflect the cost to the
applicable Banks of funding such Loan, the Agent will promptly so notify the
applicable Borrower and each applicable Bank. Thereafter, the obligation of such
Banks to make or maintain LIBOR Loans, as the case may be, hereunder shall be
suspended until the applicable Agent revokes such notice in writing. Upon
receipt of such notice, either Borrower may revoke any Notice of Borrowing or
Notice of Conversion/Continuation then submitted by it. If the applicable
Borrower does not revoke such Notice, the applicable Banks shall make, convert
or continue the Loans, as proposed by the applicable Borrower in the amount
specified in the


   51

                                      -45-

applicable notice submitted by such Borrower, but such Loans shall be made,
converted or continued as Base Rate Loans instead of LIBOR Loans.

4.06 Certificates of Banks. Any Bank claiming reimbursement or compensation
under this Article IV shall deliver to the applicable Borrower (with a copy to
applicable the Agent) a certificate setting forth in reasonable detail the
amount payable to the Bank hereunder and such certificate shall be conclusive
and binding on the applicable Borrower in the absence of manifest error.

4.07 Survival. The agreements and obligations of the Borrowers in this Article
IV shall survive the payment of all other Obligations.

                                    ARTICLE V
                              CONDITIONS PRECEDENT

5.01 Conditions of Initial Loans. The obligation of each Bank to make its
initial Loan hereunder is subject to the condition that the Canadian Agent shall
have received on or before the Closing Date all of the following, in form and
substance satisfactory to the Canadian Agent and each Bank, and in sufficient

                                   ARTICLE VI

(c)  is licensed and in good standing under the laws of each jurisdiction where
     its ownership, lease or operation of property or the conduct of its
     business requires such qualification or license; and

(d)  is in compliance with all Requirements of Law, except for those, the
     non-compliance with which would not have a Material Adverse Effect on the
     Borrower or its Subsidiaries;

6.02 Corporate Authorization; No Contravention. The execution, delivery and
performance by each Borrower and each of its Subsidiaries of this Agreement and
each other Loan Document to which such Borrower or Subsidiary is party, have
been duly authorized by all necessary corporate action, and do not and will not:

(a)  contravene the terms of any of that Borrower's or Subsidiary's Organization
     Documents;

(b)  conflict with or result in any breach or contravention of, or the creation
     of any Lien under, any document evidencing any Contractual Obligation to
     which such Borrower or Subsidiary is a party or any order, injunction, writ
     or decree of any Governmental Authority to which such Borrower or its
     property is subject other than under the Collateral Documents; or

(c)  violate any Requirement of Law, except for those, the non-compliance with
     which would not have a Material Adverse Effect on the Borrower, the
     Subsidiary or its Subsidiaries.

6.03 Governmental Authorization. No approval, consent, exemption, authorization,
or other action by, or notice to, or filing with, any Governmental Authority
(except for recordings or filings in connection with the Liens granted to the
Agents under the Collateral Documents) is necessary or required in connection
with the execution, delivery or performance by, or enforcement against, either
Borrower of the Agreement or any other Loan Document or by any of its
Subsidiaries of any Loan Document to which it is a party.

6.04 Binding Effect. This Agreement and each other Loan Document to which a
Borrower or any of its Subsidiaries is a party constitute the legal, valid and
binding obligations of such Borrower and such Subsidiary enforceable against
such Borrower and such Subsidiary in accordance with their respective terms,
except as enforceability may be limited by applicable bankruptcy, insolvency, or
similar laws affecting the enforcement of creditors' rights generally or by
equitable principles relating to enforceability.

6.05 Litigation. Except as listed on Schedule 6.05, there are no actions, suits,
proceedings, claims or disputes pending, or to the best knowledge of either
Borrower, threatened or contemplated, at law, in equity, in arbitration or

any of their respective properties which:


   57

                                      -51-


(a)  purport to affect or pertain to this Agreement or any other Loan Document,
     or any of the transactions contemplated hereby or thereby; or

     such Borrower or its Subsidiaries, would reasonably be expected to have a
     Material Adverse Effect.

been issued by any court or other Governmental Authority purporting to enjoin or
restrain the execution, delivery or performance of this Agreement or any other
Loan Document, or directing that the transactions provided for herein or therein
not be consummated as herein or therein provided.

6.06 No Default. No Default or Event of Default exists or would result from the
incurring of any Obligations by a Borrower or from the grant or perfection of

neither Borrower nor any Subsidiary is in default under or with respect to any
Contractual Obligation in any respect which, individually or together with all
such defaults, could reasonably be expected to have a Material Adverse Effect,
or that would, if such default had occurred after the Closing Date, create an
Event of Default under subsection 9.01(e).

6.07 ERISA Compliance. Except as specifically disclosed in Schedule 6.07:

(a)  Each Plan is, to the best of the US Borrower's knowledge, in compliance in

     other federal or state law. Each Plan which is intended to qualify under
     Section 401(a) of the Code has received a favorable determination letter
     from the IRS and to the best knowledge of the US Borrower, nothing has
     occurred which would cause the loss of such qualification. The US Borrower
     and each ERISA Affiliate has made all required contributions to any Plan
     subject to Section 412 of the Code, and no application for a funding waiver
     or an extension of any amortization period pursuant to Section 412 of the
     Code has been made with respect to any Plan.

(b)  To the best of the US Borrower's knowledge, there are no pending or
     threatened claims, actions or lawsuits, or action by any Governmental
     Authority, with respect to any Plan which has resulted or could reasonably
     be expected to result in a Material Adverse Effect. To the best of the US
     Borrower's knowledge, there has been no prohibited transaction or violation
     of the fiduciary responsibility rules with respect to any Plan which has
     resulted or could reasonably be expected to result in a Material Adverse
     Effect.

     Pension Plan has any Unfunded Pension Liability except as disclosed on
     Schedule 6.07; (iii) neither the US Borrower nor any ERISA Affiliate has
     incurred, or reasonably expects to incur, any liability under Title IV of
     ERISA with respect to any Pension Plan (other than premiums


   58

                                      -52-

     due and not delinquent under Section 4007 of ERISA); (iv) neither the US
     Borrower nor any ERISA Affiliate has incurred, or reasonably expects to
     incur, any liability (and no event has occurred which, with the giving of
     notice under Section 4219 of ERISA, would result in such liability) under
     Section 4201 or 4243 of ERISA with respect to a Multi- employer Plan; and
     (v) neither the US Borrower nor any ERISA Affiliate has engaged in a
     transaction that could be subject to Section 4069 or 4212(c) of ERISA.

used solely for the purposes set forth in and permitted by Section 7.12 and
Section 8.07. Neither Borrower nor any Subsidiary is generally engaged in the
business of purchasing or selling Margin Stock or extending credit for the
purpose of purchasing or carrying Margin Stock.

6.09 Title to Properties. Each Borrower and each Subsidiary have good record and
marketable title in fee simple to, or valid leasehold interests in, all real
property necessary or used in the ordinary conduct of their respective
businesses, except for such defects in title as could not, individually or in
the aggregate, have a Material Adverse Effect. As of the Closing Date, the
property of each Borrower and their Subsidiaries is subject to no Liens, other
than Permitted Liens.

6.10 Taxes. Each Borrower and their Subsidiaries have filed all federal,
provincial and other material tax returns and reports required to be filed, and
have paid all federal, provincial and other material taxes, assessments, fees
and other governmental charges levied or imposed upon them or their properties,
income or assets otherwise due and payable, except those which are being
contested in good faith by appropriate proceedings and for which adequate
reserves have been provided in accordance with GAAP. There is no proposed tax
assessment against either Borrower or any Subsidiary that would, if made, have a
Material Adverse Effect.

     circumstance or property, except those as set forth in Schedule 6.12. In

   60

                                      -54-

the foregoing is pending or threatened, and no patent, invention, device,

permit, and shall cause each Subsidiary to permit, representatives and
independent contractors of the Agents or any Bank to visit and inspect any of
their respective properties, to examine their respective corporate, financial
and operating records, and make copies thereof or abstracts therefrom, and to
discuss their respective affairs, finances and accounts with their respective
directors, officers, and independent public accountants, all at the expense of
the Borrowers and at such reasonable times during normal business hours and as
often as may be reasonably desired, upon reasonable advance notice to the
respective Borrower; provided, however, when an Event of Default exists the
Agents or any Bank may do any of the foregoing at the expense of the Borrowers

                                    THE AGENT

10.01 Appointment and Authorization; "Agent". Each (i) Canadian Bank hereby
irrevocably (subject to Section 10.09) appoints, designates and authorizes the
Canadian Agent and (ii) each US Bank hereby irrevocably (subject to Section
10.09) appoints, designates and authorizes the US Agent and/or the Canadian
Agent as applicable to take such action on its behalf under the


   77

                                      -71-

provisions of this Agreement and each other Loan Document and to exercise such
powers and perform such duties as are expressly delegated to it by the terms of
this Agreement or any other Loan Document, together with such powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
contained elsewhere in this Agreement or in any other Loan Document, each Agent
shall not have any duties or responsibilities, except those expressly set forth
herein, nor shall the Agents have or be deemed to have any fiduciary
relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the Agents.
Without limiting the generality of the foregoing sentence, the use of the term
"agent" in this Agreement with reference to an Agent is not intended to connote
any fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable law. Instead, such term is used merely as a matter of
market custom, and is intended to create or reflect only an administrative
relationship between independent contracting parties.

10.02 Delegation of Duties. An Agent may execute any of its duties under this
Agreement or any other Loan Document by or through agents, employees or
attorney's-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Agents shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

10.03 Liability of Agent. None of the Agent Related Persons shall (i) be liable
for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (ii) be responsible in any manner to any of the Banks for any recital,
statement, representation or warranty made by the Company or any Subsidiary or
Affiliate of the Company, or any officer thereof, contained in this Agreement or
in any other Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agent under or in
connection with, this Agreement or any other Loan Document, or for the value of
or title to any Collateral, or the validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document, or
for any failure of the Company or any other party to any Loan Document to
perform its obligations hereunder or thereunder. No Agent Related Person shall
be under any obligation to any Bank to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of the Company or any of the Company's Subsidiaries or
Affiliates.

10.04 Reliance by Agent.

(a)  The Agents shall be entitled to rely, and shall be fully protected in
     relying, upon any writing, resolution, notice, consent, certificate,
     affidavit, letter, telegram, facsimile, telex or telephone message,
     statement or other document or conversation believed by it to be genuine
     and correct and to have been signed, sent or made by the proper Person or


   78

                                      -72-

     Persons, and upon advice and statements of legal counsel (including counsel
     to the Company), independent accountants and other experts selected by the
     Agents. The Agents shall be fully justified in failing or refusing to take
     any action under this Agreement or any other Loan Document unless it shall
     first receive such advice or concurrence of the Majority Banks as it deems
     appropriate and, if it so requests, it shall first be indemnified to its
     satisfaction by the Banks against any and all liability and expense which
     may be incurred by it by reason of taking or continuing to take any such
     action. The Agents shall in all cases be fully protected in acting, or in
     refraining from acting, under this Agreement or any other Loan Document in
     accordance with a request or consent of the Majority Banks and such request
     and any action taken or failure to act pursuant thereto shall be binding
     upon all of the Banks.

(b)  For purposes of determining compliance with the conditions specified in
     Section 5.01, each Bank that has executed this Agreement shall be deemed to
     have consented to, approved or accepted or to be satisfied with, each
     document or other matter either sent by the applicable Agent to such Bank
     for consent, approval, acceptance or satisfaction, or required thereunder
     to be consented to or approved by or acceptable or satisfactory to the
     Bank.

10.05 Notice of Default. The Agents shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default, except with respect
to defaults in the payment of principal, interest and fees required to be paid
to the Agents for the account of the Banks, unless the Agents shall have
received written notice from a Bank or the Company referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default". The Agents will notify the Banks of its receipt of any such
notice. The Agents shall take such action with respect to such Default or Event
of Default as may be requested by the Majority Banks in accordance with Article
IX; provided, however, that unless and until the Agents have received any such
request, the Agents may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of the Banks.

10.06 Credit Decision. Each Bank acknowledges that none of the Agent Related
Persons has made any representation or warranty to it, and that no act by the
Agents hereinafter taken, including any review of the affairs of the Company and
its Subsidiaries, shall be deemed to constitute any representation or warranty
by any Agent-Related Person to any Bank. Each Bank represents to the Agents that
it has, independently and without reliance upon any Agent-Related Person and
based on such documents and information as it has deemed appropriate, made its
own appraisal of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of the Borrower and
its Subsidiaries, the value of and title to any Collateral, and all applicable
bank regulatory laws relating to the transactions contemplated hereby, and made
its own decision to enter into this Agreement and to extend credit to the
Borrower hereunder. Each Bank also represents that it will, independently and
without reliance


   79

                                      -73-

upon any Agent-Related Person and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of the Company. Except for notices,
reports and other documents expressly herein required to be furnished to the
Banks by the Agents, the Agents shall not have any duty or responsibility to
provide any Bank with any credit or other information concerning the business,
prospects, operations, property, financial and other condition or
creditworthiness of the Company which may come into the possession of any of the
Agent Related Persons.

10.07 Indemnification of Agents. Whether or not the transactions contemplated
hereby are consummated, the Banks shall indemnify upon demand the Agent Related
Persons (to the extent not reimbursed by or on behalf of the Company and without
limiting the obligation of the Company to do so), pro rata, from and against any
and all Indemnified Liabilities; provided, however, that no Bank shall be liable
for the payment to the Agent Related Persons of any portion of such Indemnified
Liabilities resulting solely from such Person's gross negligence or willful
misconduct. Without limitation of the foregoing, each Bank shall reimburse the
Agents upon demand for its ratable share of any costs or out-of-pocket expenses
(including Attorney Costs) incurred by the Agents in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement,
any other Loan Document, or any document contemplated by or referred to herein,
to the extent that the Agents are not reimbursed for such expenses by or on
behalf of the Borrower. The undertaking in this Section shall survive the
payment of all Obligations hereunder and the resignation or replacement of the
Agents.

10.08 Agents in Individual Capacity. BACAN, BofA and their Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Company and its
Subsidiaries and Affiliates as though BACAN or BofA were not the Agents
hereunder and without notice to or consent of the Banks. The Banks acknowledge
that, pursuant to such activities, BACAN, BofA or their Affiliates may receive
information regarding a Borrower or its Affiliates (including information that
may be subject to confidentiality obligations in favour of a Borrower or such
Subsidiary) and acknowledge that the Agents shall be under no obligation to
provide such information to them. With respect to its Loans, BACAN and BofA
shall have the same rights and powers under this Agreement as any other Bank and
may exercise the same as though it were not the Agent, and the terms "Bank" and
"Banks" include BACAN and BofA in its individual capacity.

10.09 Successor Agent. The Agents may, and at the request of the Majority Banks
shall, resign as Agent upon 30 days' notice to the Banks. If an Agent resigns
under this Agreement, the


   80

                                      -74-

Majority Banks shall appoint from among the Banks a successor agent for the
Banks. If no successor agent is appointed prior to the effective date of the
resignation of an Agent, the applicable Agent may appoint, after consulting with
the Banks and the Borrower, a successor agent from among the Banks. Upon the
acceptance of its appointment as successor agent hereunder, such successor agent
shall succeed to all the rights, powers and duties of the retiring Agent and the
term "Agent" shall mean such successor agent and the retiring Agent's
appointment, powers and duties as Agent shall be terminated. After any retiring
Agent's resignation hereunder as Agent, the provisions of this Article X and
Sections 11.04 and 11.05 shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was Agent under this Agreement. If no
successor agent has accepted appointment as Agent by the date which is 30 days
following a retiring Agent's notice of resignation, the retiring Agent's
resignation shall nevertheless thereupon become effective and the Banks shall
perform all of the duties of the Agent hereunder until such time, if any, as the
Majority Banks appoint a successor agent as provided for above.

10.10 Withholding Tax.

If Revenue Canada, the IRS or any other Governmental Authority of Canada or the
United States or other jurisdiction asserts a claim that an Agent did not
properly withhold tax from amounts paid to or for the account of any Bank
(because the appropriate form was not delivered or was not properly executed, or
because such Bank failed to notify the Agents of a change in circumstances which
rendered the exemption from, or reduction of, withholding tax ineffective, or
for any other reason) such Bank shall indemnify the Agents fully for all amounts
paid, directly or indirectly, by the Agents as tax or otherwise, including
penalties and interest, and including any taxes imposed by any jurisdiction on
the amounts payable to the Agents under this Section, together with all costs
and expenses (including Attorney Costs). The obligation of the Banks under this
subsection shall survive the payment of all Obligations and the resignation or
replacement of the Agents.

10.11 Collateral Matters.

(a)  The Agents are authorized on behalf of all the Banks, without the necessity
     of any notice to or further consent from the Banks, from time to time to
     take any action with respect to any Collateral or the Collateral Documents
     which may be necessary to perfect and maintain perfected the security
     interest in and Liens upon the Collateral granted pursuant to the
     Collateral Documents.

(b)  Each Bank authorizes the Canadian Agent to execute on its behalf any such
     Collateral Documents as may be necessary, including any notices or
     documents required to register the Collateral Documents in appropriate
     governmental registries or offices.

(c)  The Banks irrevocably authorize the Agents, at their option and in their
     discretion, to release any Lien granted to or held by the Agents upon any
     Collateral (i) upon termination


   81

                                      -75-

     of the Commitments and payment in full of all Loans and all other
     Obligations known to the Agents and payable under this Agreement or any
     other Loan Document; (ii) constituting property sold or to be sold or
     disposed of as part of or in connection with any disposition permitted
     hereunder; (iii) constituting property in which a Borrower or any
     Subsidiary owned no interest at the time the Lien was granted or at any
     time thereafter; (iv) constituting property leased to a Borrower or any
     Subsidiary under a lease which has expired or been terminated in a
     transaction permitted under this Agreement or is about to expire and which
     has not been, and is not intended by a Borrower or such Subsidiary to be,
     renewed or extended; (v) consisting of an instrument evidencing
     Indebtedness or other debt instrument, if the indebtedness evidenced
     thereby has been paid in full; or (vi) if approved, authorized or ratified
     in writing by the Majority Banks or all the Banks, as the case may be, as
     provided in subsection 11.01(f). Upon request by the Agents at any time,
     the Banks will confirm in writing the Agent's authority to release
     particular types or items of Collateral pursuant to this subsection
     10.11(b), provided that the absence of any such confirmation for whatever
     reason shall not affect the Agent's rights under this Section 10.11.

                                   ARTICLE XI
                                  MISCELLANEOUS

11.01 Amendments and Waivers. No amendment or waiver of any provision of this
Agreement or any other Loan Document, and no consent with respect to any
departure by a Borrower or any applicable Subsidiary therefrom, shall be
effective unless the same shall be in writing and signed by the Majority Banks
(or by an Agent at the written request of the Majority Banks) and the Borrower
and acknowledged by the Agent, and then any such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no such waiver, amendment, or consent shall,
unless in writing and signed by all the Banks and a Borrower and acknowledged by
such Agent, do any of the following:

(a)  increase or extend the Commitment of any Bank (or reinstate any Commitment
     terminated pursuant to Section 9.02);

     Document for any payment of principal, interest, fees or other amounts due

                                      -76-

(d)  change the percentage of the Commitments or of the aggregate unpaid
     principal amount of the Loans which is required for the Banks or any of
     them to take any action hereunder; or

(e)  amend this Section, or Section 2.15, or any provision herein providing for
     consent or other action by all Banks; or

(f)  discharge any Guarantor, or release any portion except as otherwise may be
     provided in the Collateral Document or except where the consent of the
     Majority Banks only is specifically provided for; and, provided further,
     that (i) no amendment, waiver or consent shall, unless in writing and
     signed by the Agent in addition to the Majority Banks or all the Banks, as
     the case may be, affect the rights and duties of the Agent under this
     Agreement or any other Loan Document, and (ii) the Fee Letters may be
     amended, or rights or privileges thereunder waived, in a writing executed
     by the parties thereto.

11.02 Notices.

(a)  All notices, requests, consents, approvals, waivers and other
     communications shall be in writing (including, unless the context expressly
     otherwise provides, by facsimile transmission, provided that any matter
     transmitted by a Borrower by facsimile (i) shall be immediately confirmed
     by a telephone call to the recipient at the number specified on Schedule
     11.02, and (ii) shall be followed promptly by delivery of a hard copy
     original thereof) and mailed, faxed or delivered, to the address or
     facsimile number specified for notices on Schedule 11.02; or, as directed
     to a Borrower or the Agents, to such other address as shall be designated
     by such party in a written notice to the other parties, and as directed to
     any other party, at such other address as shall be designated by such party
     in a written notice to a Borrower and the Agents.

(b)  All such notices, requests and communications shall, when transmitted by
     overnight delivery, or faxed, be effective when delivered for overnight
     (next-day) delivery, or transmitted in legible form by facsimile machine,
     respectively, or if mailed, upon the third Business Day after the date
     deposited into the mail, or if delivered, upon delivery; except that
     notices pursuant to Article II or XI to the Agent shall not be effective
     until actually received by the Agents.

(c)  Any agreement of the Agents and the Banks herein to receive certain notices
     by telephone or facsimile is solely for the convenience and at the request
     of the Company. The Agents and the Banks shall be entitled to rely on the
     authority of any Person purporting to be a Person authorized by the Company
     to give such notice and the Agents and the Banks shall not have any
     liability to the Company or other Person on account of any action taken or
     not taken by the Agents or the Banks in reliance upon such telephonic or
     facsimile notice. The obligation of the Company to repay the Loans shall
     not be affected in any way or to


   83

                                      -77-

     any extent by any failure by the Agent and the Banks to receive written
     confirmation of any telephonic or facsimile notice or the receipt by the
     Agents and the Banks of a confirmation which is at variance with the terms
     understood by the Agents and the Banks to be contained in the telephonic or
     facsimile notice.

11.03 No Waiver; Cumulative Remedies. No failure to exercise and no delay in
exercising, on the part of the Agents or any Bank, any right, remedy, power or
privilege hereunder, shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, remedy, power or privilege hereunder preclude any
other or further exercise thereof or the exercise of any other right, remedy,
power or privilege.

11.04 Costs and Expenses. Each Borrower shall:

(a)  whether or not the transactions contemplated hereby are consummated, pay or
     reimburse BACAN and/or BofA (including in their capacity as Agents) within
     five Business Days after demand (subject to subsection 5.01(f)) for all
     costs and expenses incurred by BACAN and/or BofA (including in their
     capacity as Agents) in connection with the development, preparation,
     delivery, administration and execution of, and any amendment, supplement,
     waiver or modification to (in each case, whether or not consummated), this
     Agreement, any Loan Document and any other documents prepared in connection
     herewith or therewith, and the consummation of the transactions
     contemplated hereby and thereby, including reasonable Attorney Costs
     incurred by BACAN and/or BofA (including in their capacity as Agents) with
     respect thereto; and

(b)  pay or reimburse the Agents, the Arranger and each Bank within five
     Business Days after demand (subject to subsection 5.01(f)) for all costs
     and expenses (including Attorney Costs) incurred by them in connection with
     the enforcement, attempted enforcement, or preservation of any rights or
     remedies under this Agreement or any other Loan Document during the
     existence of an Event of Default or after acceleration of the Loans
     (including in connection with any "workout" or restructuring regarding the
     Loans, and including in any Insolvency Proceeding or appellate proceeding);
     and

(c)  pay or reimburse BACAN and/or BofA (including in their capacity as Agents)
     within five Business Days after demand for environmental inspection and
     review, search and filing costs, fees and expenses, incurred or sustained
     by BACAN and/or BofA (including in their capacity as Agents) in connection
     with the matters referred to under subsections (a) and (b) of this Section.

11.05 Borrower Indemnification.

(a)  Whether or not the transactions contemplated hereby are consummated, the
     Company shall indemnify, defend and hold the Agent-Related Persons, and
     each Bank and each of its


   84
                                      -78-


     respective officers, directors, employees, counsel, agents and
     attorneys-in-fact (each, an "Indemnified Person") harmless from and against
     any and all liabilities, obligations, losses, damages, penalties, actions,
     judgments, suits, costs, charges, expenses and disbursements (including
     Attorney Costs) of any kind or nature whatsoever which may at any time
     (including at any time following repayment of the Loans and the
     termination, resignation or replacement of the Agents or replacement of any
     Bank) be imposed on, incurred by or asserted against any such Person in any
     way relating to or arising out of this Agreement or any document
     contemplated by or referred to herein, or the transactions contemplated
     hereby, or any action taken or omitted by any such Person under or in
     connection with any of the foregoing, including with respect to any
     investigation, litigation or proceeding (including any Insolvency
     Proceeding or appellate proceeding) related to or arising out of this
     Agreement or the Loans or the use of the proceeds thereof, whether or not
     any Indemnified Person is a party thereto (all the foregoing, collectively,
     the "Indemnified Liabilities"); provided, that the Company shall have no
     obligation hereunder to any Indemnified Person with respect to Indemnified
     Liabilities resulting solely from the gross negligence or willful
     misconduct of such Indemnified Person. The agreements in this Section shall
     survive payment of all other Obligations.

(b)  (i)  The Company shall indemnify, defend and hold harmless each Indemnified
          Person, from and against any and all liabilities, obligations, losses,
          damages, penalties, actions, judgments, suits, costs, charges,
          expenses or disbursements (including Attorney Costs and the allocated
          cost of internal environmental audit or review services), which may be
          incurred by or asserted against such Indemnified Person in connection
          with or arising out of any pending or threatened investigation,
          litigation or proceeding, or any action taken by any Person, with
          respect to any Environmental Claim arising out of or related to any
          property subject to a Mortgage in favour of the Agents or any Bank. No
          action taken by legal counsel chosen by the Agents or any Bank in
          defending against any such investigation, litigation or proceeding or
          requested remedial, removal or response action shall vitiate or any
          way impair the Company's obligation and duty hereunder to indemnify
          and hold harmless the Agents and each Bank.

     (ii) In no event shall any site visit, observation, or testing by the
          Agents or any Bank (or any contractee of the Agents or any Bank) be
          deemed a representation or warranty that Hazardous Materials are or
          are not present in, on, or under, the site, or that there has been or
          shall be compliance with any Environmental Law. Neither the Company
          nor any other Person is entitled to rely on any site visit,
          observation, or testing by the Agents or any Bank. Neither the Agents
          nor any Bank owes any duty of care to protect the Company or any other
          Person against, or to inform the Company or any other party of, any
          Hazardous Materials or any other adverse condition affecting any site
          or property. Neither the Agents nor any Bank shall be obligated to
          disclose to the Company or any other Person any report


   85

                                      -79-

          or findings made as a result of, or in connection with, any site
          visit, observation, or testing by the Agents or any Bank.

(c)  Survival; Defense. The obligations in this Section shall survive payment of
     all other Obligations. At the election of any Indemnified Person, the
     Company shall defend such Indemnified Person using legal counsel
     satisfactory to such Indemnified Person in such Person's sole discretion,
     at the sole cost and expense of the Borrower. All amounts owing under this
     Section shall be paid within 30 days after demand.

11.06 Marshaling; Payments Set Aside. Neither the Agents nor the Banks shall be
under any obligation to marshall any assets in favour of either Borrower or any
other Person or against or in payment of any or all of the Obligations. To the
extent that either Borrower makes a payment to the Agents or the Banks, or the
Agents or the Banks exercise their right of set-off, and such payment or the
proceeds of such set-off or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required (including
pursuant to any settlement entered into by the Agents or such Bank in its
discretion) to be repaid to a trustee, receiver or any other party, in
connection with any Insolvency Proceeding or otherwise, then (a) to the extent
of such recovery the obligation or part thereof originally intended to be
satisfied shall be revived and continued in full force and effect as if such
payment had not been made or such set-off had not occurred, and (b) each Bank
severally agrees to pay to the Agents upon demand its pro rata share of any
amount so recovered from or repaid by the Agents.

11.07 Successors and Assigns. The provisions of this Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns, except that neither Borrower may assign or transfer any
of its rights or obligations under this Agreement without the prior written
consent of the Agents and each Bank.

11.08    Assignments, Participations, etc.

(a)  Any Bank may, with the written consent of the Agents, and the Company,
     which consent shall not be unreasonably withheld, at any time assign and
     delegate to one or more Eligible Assignees (each an "Assignee") all, or any
     ratable part of all, of the Loans, the Commitments and the other rights and
     obligations of such Bank hereunder, in a minimum amount of $5,000,000;
     provided, however, that (i) a Canadian Bank will assign only to another
     Canadian Bank capable of making loans in Canadian Dollars and Dollars in
     Canada, and a US Bank will assign only to another bank capable of making
     loans in Dollars in the United States; (ii) the applicable Borrower and the
     Agent may continue to deal solely and directly with such Bank in connection
     with the interest so assigned to an Assignee until (A) written notice of
     such assignment, together with payment instructions, addresses and related
     information with respect to the Assignee, shall have been given to the
     applicable Borrower and the Agent by such Bank and the Assignee; (B) such
     Bank and its Assignee shall have delivered to the applicable Borrower and
     the Agent an Assignment


   86
                                      -80-


     and Acceptance in the form of Exhibit D ("Assignment and Acceptance") and
     (c) the assignor Bank or Assignee has paid to the Agent a processing fee in
     the amount of $3,500;

(b)  From and after the date that the Agent notifies the assignor Bank that it
     has received (and provided its consent with respect to) an executed
     Assignment and Acceptance and payment of the above-referenced processing
     fee, (i) the Assignee thereunder shall be a party hereto and, to the extent
     that rights and obligations hereunder have been assigned to it pursuant to
     such Assignment and Acceptance, shall have the rights and obligations of a
     Bank under the Loan Documents, and (ii) the assignor Bank shall, to the
     extent that rights and obligations hereunder and under the other Loan
     Documents have been assigned by it pursuant to such Assignment and
     Acceptance, relinquish its rights and be released from its obligations
     under the Loan Documents.

(c)  Any Bank may at any time sell to one or more commercial banks or other
     Persons not Affiliates of the Company (a "Participant") participating
     interests in any Loans, the Commitment of that Bank and the other interests
     of that Bank (the "originating Bank") hereunder and under the other Loan
     Documents; provided, however, that (i) the originating Bank's obligations
     under this Agreement shall remain unchanged, (ii) the originating Bank
     shall remain solely responsible for the performance of such obligations,
     (iii) the Borrower and the Agents shall continue to deal solely and
     directly with the originating Bank in connection with the originating
     Bank's rights and obligations under this Agreement and the other Loan
     Documents, and (iv) no Bank shall transfer or grant any participating
     interest under which the Participant has rights to approve any amendment
     to, or any consent or waiver with respect to, this Agreement or any other
     Loan Document, except to the extent such amendment, consent or waiver would
     require unanimous consent of the Banks as described in the first proviso to
     Section 11.01. In the case of any such participation, the Participant shall
     not have any rights under this Agreement, or any of the other Loan
     Documents, and all amounts payable by the Borrower hereunder shall be
     determined as if such Bank had not sold such participation; except that, if
     amounts outstanding under this Agreement are due and unpaid, or shall have
     been declared or shall have become due and payable upon the occurrence of
     an Event of Default, each Participant shall be deemed to have the right of
     set-off in respect of its participating interest in amounts owing under
     this Agreement to the same extent as if the amount of its participating
     interest were owing directly to it as a Bank under this Agreement.

(d)  Notwithstanding the provisions of this Article XI, if there shall have
     occurred an Event of Default that is continuing, a Bank may make any
     assignment or sell participations to any bank, financial institution or
     commercial lender, whether an Eligible Assignee or not, and no consent
     shall be required therefor.

(e)  Notwithstanding any other provision in this Agreement, any US Bank may at
     any time create a security interest in, or pledge, all or any portion of
     its rights under and interest


   87

                                      -81-

     in this Agreement in favour of any Federal Reserve Bank in accordance with
     Regulation A of the FRB or US Treasury Regulation 31 CFR ss.203.14, and
     such Federal Reserve Bank may enforce such pledge or security interest in
     any manner permitted under applicable law.

11.09 Confidentiality. Each Bank agrees to take and to cause its Affiliates to
take normal and reasonable precautions and exercise due care to maintain the
confidentiality of all information identified as "confidential" or "secret" by a
Borrower and provided to it by a Borrower or any Subsidiary, or by the Agents on
the Company's or such Subsidiary's behalf, under this Agreement or any other
Loan Document, and neither it nor any of its Affiliates shall use any such
information other than in connection with or in enforcement of this Agreement
and the other Loan Documents or in connection with other business now or
hereafter existing or contemplated with a Borrower or any Subsidiary; except to
the extent such information (i) was or becomes generally available to the public
other than as a result of disclosure by the Bank, or (ii) was or becomes
available on a nonconfidential basis from a source other than a Borrower,
provided that such source is not bound by a confidentiality agreement with a
Borrower known to the Bank; provided, however, that any Bank may disclose such
information (A) at the request or pursuant to any requirement of any
Governmental Authority to which the Bank is subject or in connection with an
examination of such Bank by any such authority; (B) pursuant to subpoena or
other court process; (c) when required to do so in accordance with the
provisions of any applicable Requirement of Law; (D) to the extent reasonably
required in connection with any litigation or proceeding to which the Agents,
any Bank or their respective Affiliates may be party; (E) to the extent
reasonably required in connection with the exercise of any remedy hereunder or
under any other Loan Document; (F) to such Bank's independent auditors and other
professional advisors; (G) to any Participant or Assignee, actual or potential,
provided that such Person agrees in writing to keep such information
confidential to the same extent required of the Banks hereunder; (H) as to any
Bank or its Affiliate, as expressly permitted under the terms of any other
document or agreement regarding confidentiality to which a Borrower or any
Subsidiary is party or is deemed party with such Bank or such Affiliate; and (i)
to its Affiliates.

11.10 Set-off. In addition to any rights and remedies of the Banks provided by
law, if an Event of Default exists or the Loans have been accelerated, each Bank
is authorized at any time and from time to time, without prior notice to a
Borrower any such notice being waived by a Borrower to the fullest extent
permitted by law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final) at any time held by, and other
indebtedness at any time owing by, such Bank to or for the credit or the account
of a Borrower against any and all Obligations owing to such Bank, now or
hereafter existing, irrespective of whether or not the applicable Agent or such
Bank shall have made demand under this Agreement or any Loan Document and
although such Obligations may be contingent or unmatured. Each Bank agrees
promptly to notify a Borrower and the applicable Agent after any such set-off
and application made by such Bank; provided, however, that the failure to give
such notice shall not affect the validity of such set-off and application.


   88

                                      -82-

11.11 Notification of Addresses, Lending Offices, Etc. Each Bank shall notify
the Agents in writing of any changes in the address to which notices to the Bank
should be directed, of addresses of any Lending Office, of payment instructions
in respect of all payments to be made to it hereunder and of such other
administrative information as the Agents shall reasonably request.

11.12 Counterparts. This Agreement may be executed in any number of separate
counterparts, each of which, when so executed, shall be deemed an original, and
all of said counterparts taken together shall be deemed to constitute but one
and the same instrument.

11.13 Severability. The illegality or unenforceability of any provision of this
Agreement or any instrument or agreement required hereunder shall not in any way
affect or impair the legality or enforceability of the remaining provisions of
this Agreement or any instrument or agreement required hereunder.

11.14 No Third Parties Benefited. This Agreement is made and entered into for
the sole protection and legal benefit of each Borrower, the Banks, the Agents
and the Agent-Related Persons, and their permitted successors and assigns, and
no other Person shall be a direct or indirect legal beneficiary of, or have any
direct or indirect cause of action or claim in connection with, this Agreement
or any of the other Loan Documents.

11.15 Governing Law and Jurisdiction.

(a)  THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
     LAW OF THE PROVINCE OF ONTARIO AND THE FEDERAL LAWS OF CANADA APPLICABLE
     THEREIN.

                                      -83-

11.16 Entire Agreement. This Agreement, together with the other Loan Documents,
